There is also a misconception by people that a 1031 is "avoiding taxes".

The popular misconception is that a property either cashflows or appreciates, not both.

I know that many people have misconceptions about being a RE Agent that they make a lot of money.

Also, listen to house hacking podcasts to further your education and prepare you.One misconception I had when I purchased my first property was that finding the deal and closing it would be the hardest part and, once I got past that, it would be easy.

@Ray Tapay The thought that you will get better clientele (Tenants) in one city/town as opposed to another is a big misconception that's made by many newer investors (and some OGs).

I think there is a mis-conception that things like depreciation are some "super special advantage".

Also it seems to be a common misconception that REOs will be free and clear titles, but ive read that seems to not always be true.

You don't need an LLC for tax purposes either (a common misconception) because all the rental activity will be on your personal K1. 

I find this is a common misconception that new investors have. 

I have this misconception that realtors and investors are separated by a stream...it seems that working together would be the ABSOLUTE last resort for both parties.
